Description

The RC32514A is a small, low-power timing component designed to be placed immediately adjacent to a PHY, switch, ASIC, or FPGA that requires several reference clocks with a jitter performance of less than 100fs. The RC32514A can act as a frequency synthesizer to locally generate the reference clock, a jitter attenuator to perform local clean-up, and/or frequency translation of a centrally-supplied reference, a synchronous Ethernet equipment clock to perform passband filtering and clean-up of network-supplied references or as a digitally controlled oscillator (DCO) for frequency margining or OTN clock applications. It contains an internal crystal that can be leveraged as the frequency reference for the onboard PLL if desired.
